Research and Construction of Clock Synchronization Hybrid Network Architecture for UHD IP System
Jinan Radio and Television Station has established a collaborative innovation test platform dedicated to exploring UHD media applications.Through extensive research in areas such as UHD and IP-based broadcasting,media convergence,and intelligent applications,the station has laid a solid technical groundwork for the development of UHD systems.Leveraging test experiences,protocol specifications,and equipment capabilities,our test platform successfully deployed a high-precision,fully redundant,and low-latency PTP system.Furthermore,we extended this setup to embrace a hybrid network architecture incorporating NTP,LTC,and BB synchronization methods.Our comprehensive solution has demonstrated promising application outcomes.This paper delves into the analysis and elucidation of the clock-synchronous hybrid network architecture,offering valuable insights and practical guidance for the construction of UHD IP broadcasting systems in the radio and television domain.
